CHELSEA have a battle on their hands in their bid to tie Thibaut Courtois on a permanent deal.

The Belgian shot stopper has been in sensational form for Atletico Madrid during his two seasons on loan at the Vicente Calderon and has already tasted success, having lifted the Europa League and European Super Cup titles.

Courtois’ parent club missed out on Jack Butland in the January transfer window and they are in need of suitable cover.

Furthermore, Courtois left Chelsea to get more regular football and he has realised his wish at Atletico.

But Spanish football site Inside Spanish Football explains Chelsea want to bring Courtois back to London and are prepared to offer him a more lucrative deal.

They also point out that Barcelona are keeping an eye on Courtois, as Victor Valdes’ future at the Camp Nou remains in doubt.

Courtois has kept four cleans sheets in his last six La Liga games for Atletico.
